“…While the extent to which traumatic events affect individuals varies (e.g., Kamphuis & Emmelkamp, 1998;Deffenbacher et al, 2004;Salmon & O'Kearney, 2014) some, perhaps most, of these victims and witnesses will be traumatised (e.g., Campbell et al, 2009;Jakobsen et al, 2016;Lui et al, 2017). While the contribution of rapport to the process and product of an investigative interview has been recognised in the research and guidance for some time (e.g., Milne & Bull, 1999;Collins et al, 2002;St-Yves, 2006;Fisher & Geiselman, 2010;Kim et al, 2020), its importance in the management of trauma has recently been emphasised (e.g., Smith & Milne, 2018;Risan et al, 2020;Jakobsen, 2021).…”
